Natural Park Aquarium Boat Trip

This three-hour Natural Park Aquarium boat trip departs from San Antonio's port at 11:00am, heading northwest along Ibiza's rugged coastline. Your first stop is Cap Blanc Aquarium, an extraordinary sea cave that once served as a lobster nursery and now reveals endemic species of the Pityusic waters through its glass-bottom viewing. The route takes you past Cala Gració, Cala Gracioneta, Cala Salada, Saladeta and Punta Galera—each a distinct cove with its own character. The journey concludes at Margaritas Islands, a protected nature reserve where you'll swim for roughly 45 minutes with snorkelling equipment and glass-bottom boat access. Between the water and the boat, you'll see what lives beneath the surface without needing to dive deep. Fruit and savoury snacks arrive after, along with drinks throughout: water, soft drinks, sangria, white wine and beer. Departures run Mondays, Wednesdays, Thursdays and Saturdays. Check in at the Captain Nemo kiosk in Puerto de San Antonio, opposite the Egg roundabout, arriving 30 minutes before departure.
